A president not sure of what he wants complicates the shutdown impasse

And twice over the past two weeks, Mr. Trump has privately told lawmakers he is eager to strike a deal to extend legal status to the so-called Dreamers, only to have his chief of staff, John F. Kelly, and senior policy adviser, Stephen Miller, make clear afterward that such a compromise was not really in the offing — unless it also included a host of stiffer immigration restrictions.

As the government shutdown continued for its second day on Sunday, one thing was clear to both sides of the negotiations to end it: The president was either unwilling or unable to articulate the immigration policy he wanted, much less understand the nuances of what it would involve.

Both sides have reason to be confused. Each time Mr. Trump has edged toward compromise with Democrats, he has appeared to be reined in by his own staff, which shares the hawkish immigration stance that fueled his campaign. And Republican leaders, bruised by past experience with a president who has rarely offered them consistent cover on a politically challenging issue, are loath to guess at his intentions.
